How Do I Stop Regenerating Models in AutoCAD?

by

Are you tired of AutoCAD constantly regenerating your models? It can be frustrating, especially when you’re trying to work efficiently.

But fear not, there are ways to stop AutoCAD from regenerating your models and improve your productivity. In this tutorial, we will explore different methods to tackle this issue.

Method 1: Adjusting the REGENAUTO System Variable

If you want more control over when AutoCAD regenerates your models, you can adjust the REGENAUTO system variable. This variable determines whether AutoCAD automatically regenerates models when changes are made. By default, REGENAUTO is set to 1, which means that AutoCAD regenerates models automatically.

To change the value of the REGENAUTO system variable:

  1. Open the Command Line in AutoCAD by pressing Ctrl + 9 or by clicking on the Command Line icon at the bottom of the screen.
  2. Type REGENAUTO and press Enter.
  3. The current value of REGENAUTO will be displayed. If it is set to 1, it means that AutoCAD is regenerating models automatically.
  4. To stop AutoCAD from regenerating models automatically, type REGENAUTO again followed by a space and then type 0. Press Enter.

Note: Setting REGENAUTO to 0 means that you will have to manually regenerate models using the REGEN command whenever necessary.

Method 2: Using the REGEN Command Manually

If you prefer manually controlling when AutoCAD regenerates your models, you can use the REGEN command. The REGEN command forces a regeneration of all objects in the drawing.

To use the REGEN command:

  1. Open the Command Line in AutoCAD.
  2. Type REGEN and press Enter.
  3. All objects in the drawing will be regenerated, and any changes you have made will be updated.

Note: The REGEN command can also be used with additional options, such as REGENALL and REGENAUTO. These options allow you to regenerate all drawings or set AutoCAD to regenerate automatically after executing certain commands.

Method 3: Adjusting the VIEWRES System Variable

The VIEWRES system variable controls the smoothness of curved and non-curved objects in AutoCAD. By adjusting this variable, you can improve performance and reduce the need for constant regeneration.

To change the value of the VIEWRES system variable:

  1. Open the Command Line in AutoCAD.
  2. Type VIEWRES and press Enter.
  3. The current value of VIEWRES will be displayed. The default value is set to 1000.
  4. To reduce the need for regeneration, you can decrease this value by typing a smaller number (e.g., 500). Press Enter to apply the new value.

Note: Lowering the VIEWRES value may result in less smooth curves, but it can significantly improve performance when working with large drawings or complex models.

In Conclusion

In this tutorial, we have explored different methods to stop AutoCAD from regenerating models automatically. By adjusting system variables like REGENAUTO and VIEWRES, you can have more control over when and how AutoCAD regenerates your models. Remember to find the right balance between performance and visual quality for your specific needs.

Now that you are equipped with these techniques, you can work more efficiently and reduce the frustration of constant model regeneration in AutoCAD.
